To @ZZ whom it may concern:

Be it known that l, JOHN A. MOSHER, a citi- Zen ot' the United States,and a resident of Chicago, county of Cook, and State of illinois, haveinvented certain new and useful improvements in Roll-Holders, of whichthe following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof, and in which- Figure l isa rear elevation of the rollholder, partly in section, with its backplate removed. Fig. 2 is a sectional view on the line 2 2 of Fig. 1.Fig. 3 is a plan View ou the line 3 3 of Fig. l. Fig. iis a detail frontelevation of the roll-holder When open. Fig. 5 is a sectional view onthe line 5 5 of Fig. 1. Fig. 6 is a detail of a part of the roll-holder.Figs. 5 and 6 are drawn upon a larger scale than the remainder of thefigures.

The invention relates to roll-holders for that class of hand-cameras inwhich the sensitized medium is inclosed within a lightproof case 'havinga hinged cover and in which mechanism is provided for opening andclosing this cover from without the case.

The object of the invention is to provide an improved form ofroll-holder particularly for use in connection with this type of canera, but having features also which may be applied to various styles ofinstruments.

This invention consists in the peculiar form of roll-holder herein shownand described and possessing the various novel features of construction,as hereinafter set forth.

The camera-case A has au openable seotion B, which, as shown,isapproximately onehalf ot the top side of the oblong rectangular case,being hinged at h to the remainder of this side of the case and beingprovided with a suitable clasp for engagement with the rear end o of thecase.

The roll-holder C is an oblong rectangular box, preferably made ofmetal, adapted to fit Within the rearward end of a cameraoase, beingprovided at its forward edge with lateral wings c, adapted to enter thevertical grooves or ways in the inner faces of the side Walls of thecase. The rearward side C of the roll-holder is provided with acontinuous Iiange adapted to frictionally engage the body portion, andthe front wall D of the rollholder,being the supporting-plate for thesensitized ilm, has at each end a vertical slot through which the film Fpasses, and immodiately back of each of these slots is located auantifrictiou-roller E E', over which the film is turned. rThe film F isplaced within the roll-holder upon the spool G and is transferred to thespool H, also mounted within the rol l-h older, by being passed over theouter surface of the plate D.

The front of the roll-holder is provided with a cover J hinged acrossits lower edge to the lower edge of the roll-holder, as indicated at j,and provided with a continuous flange J at its edges, turned inwardlytoward the face of the roll-holder, the hinge-platej being extendeddownwardly beyond the lower edge ol the cover. The plate Dis providedwith a continuous groove d near its edges, adapted to receive the flangeJ, so as to make therewith a lighttight joint. The upper edge of theplate D is turned forwardly and is provided with beaded portions, asshown at d', with which cooperate friction-clasps J 3, formed upon theupper end of a plate J2, secured to the outer face of the cover J acrossits top edge, this plate being provided with a thumb-piece J5, by whichit may be conveniently opened. The ends of the plate J2 project beyondthe edge of the cover J, as shown at J 4, so that when the roll-holder Cis inserted within a camera-case, its wing-pieces c sliding withingrooves or ways in the side walls, the projections Jl afford means forengaging' with suitable opening mechanism of a camera.

The roll-holder .is so constructed that the spools upon which the filmsnow in general use are sold may be mounted within it. These spools areusually provided with central end sockets to receive trunnions fixedwithin the roll-holder. Such a trunnion gis set in the top of the case Cto engage the upper end of the spool Gr. Preferablya friction-plate g isfixed upon the trunnion c/ The upper end of the spool l-l is engaged bya similar trunnion m, being the prolongation of a stud-shattjournaled inthe top ot' the case C and carrying a ratchet-wheel M, with whichcooperates a pawl C, held to the ratchet-wheel by the spring o. Meansare provided for positively IOO interlocking the ratchet-wheel and spoolH, so that they will rotate together. As shown, this is accomplished bylocating studs m of any desired number on the disk face of the wheel M,so that they will engage the end of the spool. The lower trunnion p foreach spool is mounted upon a plate P, carried by a sleeve p, mountedloosely upon a post Q, firmly set in the top and bottom of the case C. Acontracting-spring q is wound upon the upper end of each of the posts Qand secured atits upper end to the post and at its lower end to thesleeve pl, so that it draws the plate P upwardly. A stem P projectsbackwardly from each of the plates P and is held under a guide orretaining plate R, secured to the bottom of the case C and resisting`the pull of the spring q. The plate R is provided with a recess r foreach of the stems P, so located that these stems enter them when theplates P are swung to such position that the trunnions p, carried bythem, are in line with the trunnions g m, respectively. The recess r isof such depth that it allows the plates P to bear with the full strengthof the springs q upon the spools. The spools are readily inserted withinthe roll-holder by swinging the plates outwardly to the position shownby dotted lines in Fig. 3, placing the spools upon them and turning themback into the case. As the stems P enter the recess r the plates P riseand bring the spools into engagement with the upper trunnions. Therecess r serves the further purpose of preventing accidental angularmovement of the plates P. The upper end of the shaft m carries aturn-button iN by means of which the spool H may be rotated to transferthe film from the spool G. The ratchet and pawl M O prevent the reversemotion of the spool H, and the friction of the spool Gr upon thespring-controlled plate P, supporting it, and the plate g provides forthe necessary tension of the film.

Any desired means forindicating the movement of the iilm may beemployed. The most approved method of mounting films now in vogue isthat in which there is employed a backing of opaque material interrolledupon the spool with lm, and upon this backing indicating` characters forthe several sections of the film are plainly marked. In order to exposethese characters to the view of the operator,there is provided anobserving-aperture in the plate J and another in the top of the case C,as shown at S, and these are connected by a tube s, so that as theturn-button M is rotated the character marking the next section of thefilm to be brought to the position of exposure may be readily seen.

I claim as my invention- 1. In a roll-holder, a case adapted to containa pair of spools and having a plate D over which a film may be drawn forexposure, such plate and one of the walls of the case perpendicularthereto each having an observingaperture, opaque walls inclosing theline of vision from one of said apertures to the other, and a hingedcover for the plate D.

2. ln a roll-holder, the combination with a case, of a fixed trunnionmounted within the case for receiving one end of a film-spool, and afriction-plate for receiving the opposite end of the spool and beingpivotally mounted in the case to swing in the plane of its frictionalbearing-face.

3. The combination with a roll-holder case, of a iixed spool-receivingtrunnion mounted within the case, a lixed post parallel with the trunnion, a sleeve mounted to slide and rotate upon the post,afriction-plate carried by the sleeve for cooperating with the fixedtrunnion to hold the spool, and a spring for forcing the plate towardthe trunnion.

A. The combination with a roll-holder case, of a fixed spool-receivingtrunnion within the case, a swinging friction-plate for engaging theopposite end of the spool, and being adapted to slide longitudinallyupon its pivot, and a spring for forcing the plate toward the lixedtrunnion.

5. The combination with a roll-holder case, of a rod within the case, asleeve mounted upon and in sliding engagement therewith, afriction-plate for carrying a film-spool and having a stud upon whichthe spool may rotate, such plate being capable of an oscillatingmovement about the rod, a stem projecting radially from the sleeve, aguide-plate for such stem and having a lateral recess, a spring actingupon the sleeve in opposition to the guide-plate, and a trunnion mountedwithin the case for cooperating with the frictionplate to hold thespool.

6. ln a roll-holder, the combination with a case, of a pair ofoscillating plates for supporting the film-spools, a fixed trunnion forreceiving 'the upper end of the deliveringspool, a rotatable trunnionfor engaging and interlocking with the receiving-spool, and beingcontrollable from without the case, and springs for forcing theoscillating plates upwardly.

7. ln a roll-holder, the combination with a case, of a pair of posts setacross the interior of the case, a sleeve mounted loosely upon eachpost, a supporting-plate projecting radially from each sleeve andadapted to rotatably carry a iilm-spool, a stem projecting from eachplate, a fixed guide-plate foreach stem, and having a lateral recess,studs mounted within the case to cooperate with the supporting-platesfor carrying the spools, and springs forcing the plates toward thestuds.
